  Log:
  MFC rev. 1.48:
  (reinit_bus): When the ATAPI bus is reset, do not schedule an automated
   CAM rescan if the ATAPI device entries have not changed.
  
  The ATAPI bus may be reset for a variety of reasons, including any time an
  ATAPI request times out. It is not necessary to rescan at the CAM level
  in such a case, unless a device has appeared or disappeared, or has
  otherwise changed.
  ---
  MFC revs. 1.49 and 1.50:
  (atapi_action): Improve error reporting by removing ATA_R_QUIET flag
   from ATAPI requests. If CAM debugging is enabled, also mark ATAPI
   requests with ATA_R_DEBUG flag.
  
  (atapi_cb): Report ATAPI timeouts to the CAM layer.
   Fix incorrect debugging traces in the presence of ATAPI errors.
